Is it possible to get a full facial Botox treatment?

As I get older, my skin elasticity decreases and fine wrinkles increase, making it difficult to maintain a youthful appearance. I am particularly concerned because the wrinkles around my eyes and forehead are deepening, making me look tired and older. That is why I have been looking into Botox treatments lately, and my question is whether it is possible to receive Botox injections for the entire face.

I have heard that the procedure is usually performed on specific areas such as the forehead, between the eyebrows, or around the eyes, but I am concerned about whether it is possible to treat the entire face, including the jawline and around the cheeks, and whether natural facial expressions can be maintained if done so. If anyone has received full-face Botox, it would be very helpful if you could share your experiences regarding satisfaction, effectiveness, and whether you experienced any discomfort after the procedure. I want to maintain a youthful image, so I am struggling to decide which option would be the wise choice.
